First and foremost a real focus on managing water during and after construction, is to me real critical to doing good development. I like to use that the model of the native ecosystem, the landscape a couple hundred years ago, and I know we're not going to turn the whole world back into prairie of course but I do think we can understand how water might once have moved through this natural or native ecosystem and I think we can design new developments that will mimic the way that landscape functioned - even if it doesn't look like it once did I think it can behave or function very similar to that.
